this light does dim, and theoretically is perfect. as per normal, you need to turn your dimmer down just a bit from full and it will not flicker. the downside is the colour, it has a green hue which makes everyone look jaundice and ill. I was hoping it would be proper 2800, but is nowhere near anything on the Kelvin Scale.

UPDATE: since posting this, i was offered a complete refund to return the bulbs, very impressed. Miniinthebox is like the Chinese Amazon - they just need to get someone to give more accurate product descriptions!
